Each selected bunker has a safe which contains historical documents concerning apects of the Second World War pertinent to the respective region. A list of contemporary weapons and conflicts will lie on the upper level. As a reminder of the historic origin of the Phytobunker, and to costantly reevaluate of the facts, the safe is displayed once a year. So as not activate a climate of the hate and the fear, and to prevent a spiral of violence, the exhibitons are only open for a limited duration.
